Development of direct digital control for ethanol fermentation process

Abstract

In any process, good production rate, high purity product, efficient and safe operation can not be guaranteed unless a good process control system is installed. However, in developing a sensitive process control scheme, accurate process description is required. This is particularly difficult in biological processes because the dynamics are normally nonlinear, non stationary and time varying. One approach to this class of problem is by employing recursive estimation techniques and this paper will illustrate its application on ethanol fermentation. The study started with simulation works and actual experimental activities are under formulation.
